I have a 1991 Johnson 115 and am currently replacing the water pump (1st time for me with this engine), I have the manual and have located the bolt that connects the lower unit shift rod to the shifter linkage ( under the lower carb). I must be missing something because it looks like a bear to get at. The manual says to remove the starter but that quite doesn't seem to help much. I've read a bunch of posts that all seem to say the same thing, just dissconnect the linkage bolt, no trouble. It looks like to me that the carbs need to be dropped to gain access. Seems like too much work..what do you think....<br />seb
